Mam 2 modele

class DestinationDescription
...
has_many :destinations, 
         :class_name => 'Destination',
         :foreign_key =>'Destination_ID'
              
i

class Destination
...
belongs_to :destination_descriptions, 
           :class_name => 'DestinationDescription', 
           :foreign_key=> 'Destination_ID'     

Sprawdzam z konsoli:

>> dd = DestinationDescription.find :first
>> dd.Destination_ID # => 93
>> d = Destination.find :first, :conditions => 'Destination_ID=93'
>> d.Destination_ID # => 93

Czyli dane w tabeli maja sens. A teraz najgorsze:

>> dd.destinations # => []
>> dd.destinations_count # => 0 ZERO!!!

Co tu jest nie tak? Dlaczego nie ma danych?

Podeslij dumpy z w/w tabel, bo inaczej to ciezko powiedziec co moze byc
nie tak (rozumiem ze obie klasy dziedzicza z ActiveRecord::Base tylko
nie zaciemniales opisu).
